A compound of the formula:
wherein,
Z1 & Z2 are each independently - 0 -, -S- or - NR5 - in which R5 is H or an optionally-substituted hydrocarbon group or an acyl group;
X1 & X2 are selected from H, cyano, C1 4-alkyl, C1 4-alkoxy, aryl, carbamoyl, sulphamoyl, carboxylic acid or carboxylic acid ester;
R1 toR4 are each independently selected from H, C1-4-alkyl, C1-4-alkoxy, C1-4-alkenyl, halogen and the group -X- Y;
X is -O- or -S-; and
Y is C2 10-alkenyl
provided that,
the substituents on rings A & B are different when Z1 & Z2 are the same or that Z1 & Z2 are different when the substituents on rings A & B are the same,
which is suitable for the coloration of synthetic textile materials and processes for its preparation.
